DescriptionThe entire electrical system has been designed and constructed in accordance with the most up-to-date guidelines concerning safety and protection, especially against fire risks.There are two main kinds of protection:active protection, aimed at reducing possible causes of faults 'at source';passive protection, aimed at minimizing the effects of a possible fault.The first kind involves the thoughtful design of wiring, attentive to location and anchorage, and the careful planning of properly protected cable routes.Modifications have therefore been made to the alternator and starter motor cables, with the adoption of protective caps, etc.Passive protection instead includes all the interventions, which have always been adopted on vehicles, to reduce high fault currents (overload and short circuit).All the fuses included in the system have been rated on the basis of the nominal absorption of the loads which cannot be served simultaneously, and so as to ensure intervention in the case of a definite short circuit.All the electrical systems are supplied by the battery at a voltage of 12. V. The battery is in turn recharged by the alternator ( 3309762SeeE5010STARTING AND RECHARING ) during engine operation. The main supply lines are protected by 'MAXIFUSES', grouped together in a container located in the engine compartment services compartment.The power supplies to all services and systems are protected by fuses grouped in the junction units, one of which is inside the passenger compartment and the other one which is in the engine compartment on the left side panel. The unattached fuses are located in the engine compartment near the rear bulkhead and in compartments protected by covers in the luggage compartment, one on the right hand side and the other on the left hand side behind the battery.All the power supplies are thus protected, except for the starter motor cable (battery-starter motor) and recharging cable (starter motor-alternator): these are protected by an additional shielded sheath.Some circuits are supplied continuously, even if the vehicle is stopped and the ignition is off, as they are connected directly to the battery.Other circuits are supplied by turning the ignition key to various different positions:when the key is inserted and turned to the first click, the ignition is turned on (MAR position) and several circuits are supplied, which are thus called 'ignition-operated' (lines 'INTE' and '15/54');the second click - AVV (starting) position - supplies the starter motor (line '50'), disconnecting certain circuits (those which absorb greater power) and thereby guaranteeing the maximum current flow to the actual starter motor; ('INT/A' line).767The lines through which the supply is distributed to the various electrical devices are shown on the wiring diagrams relating to the various functions and systems.This general diagram shows all the lines which depart from the battery and the MAXIFUSE boxes; reference should be made to the specific diagrams for greater detail.
Functional descriptionAll electrical equipment and systems are supplied by battery A1, located in the boot compartment: two junction units distribute power to the various parts of the car.junction unit A6 is located at the rear. This is protected by MAXIFUSE for rear services B4 (60A). It sends power to all services with control units or systems located in the boot compartment.terminal board A5 is located at the front - in the engine bay. This is protected by master power supply MAXIFUSE B2 (125A). It sends power to all services with control units or systems located in the engine bay.The other supply lines leading to junction unit B1 and ignition switch H1 are protected by both MAXIFUSES B5:ACC (30A) for supply to ignition switch H1 ;CENTR (60A) for supply for services via fuses for junction unit B1Other circuits are supplied by turning ignition key H1 to various different positions:certain ignition-operated services are supplied when the key is turned to MAR;in the AVV position - the starter motor is supplied; (line '50') (3309762SeeE5010STARTING AND RECHARING);certain services which are ignition-operated except at start-up are disconnected in this position (INT/A line)
